Global bifurcation of solutions for a predator-prey model with prey-taxis. (English) Zbl 1307.92333
Summary: We study pattern formations in a predator-prey model with prey-taxis. It is proved that a branch of nonconstant solutions can bifurcate from the positive equilibrium only when the chemotactic is repulsive. Furthermore, we find the stable bifurcating solutions near the bifurcation point under suitable conditions.
